The world's most perfect dress pants
I have purchased several of these pairs of pants over the last few years at my job. I wear these pants every shift. They were great. They fit perfect and don't wrinkle or need ironed, that's a huge plus. I work 12 hour shifts in a hospital in a non medical role. So, these are dress pants, not work pants but they wear really well and do not show wear. I have worn other brands that have come apart. These are top of the line and the only pants I wear at my job. They are not not at all hot to wear either. Please, try a pair and I hope you love them.

Excellent Big/Tall Dress Pant
Very comfortable and stretchy pant for a big man. The fabric is breathable but not sheer or feeling like it's going to rip. The button and clasp enclosure made the waist feel extra sturdy. Plenty of stretch to tuck your shirt back in without any obnoxious grunting or groaning. The cut of the legs/thighs is generous with a slight taper towards the bottom cuff. You don't even need to hike them up to sit down comfortably. The pockets are deep enough for any phone or wallet. This is an excellent budget option for guys who don't go to many formal events but still want to look nice.
